Good stuff, but I hope they won't be showing all of the 50 something imprints, 6 or so should be more than enough to demonstrate. Even if he does end up fighting all 50 of them.
academy headmaster: "if the kid defeats my imprint, his tutor will be a swordswoman-master, and he will be her assistant, commanding all outer students."
other deans: "huh, is this "Spirit Sword Sovereign"?"
